-**  Time scale transformation:  Terrestrial Time, TT, to International
-**  Atomic Time, TAI.
-**
-**  Given:
-**     tt1,tt2    double    TT as a 2-part Julian Date
-**
-**  Returned:
-**     tai1,tai2  double    TAI as a 2-part Julian Date
-**
-**  Returned (function value):
-**                int       status:  0 = OK
-**
-**  Note:
-**
-**     tt1+tt2 is Julian Date, apportioned in any convenient way between
-**     the two arguments, for example where tt1 is the Julian Day Number
-**     and tt2 is the fraction of a day.  The returned tai1,tai2 follow
-**     suit.

-**  
-**  The ERFA version is intended to retain identical functionality to
-**  the SOFA library, but made distinct through different function and
-**  file names, as set out in the SOFA license conditions.  The SOFA
-**  original has a role as a reference standard for the IAU and IERS,
-**  and consequently redistribution is permitted only in its unaltered
-**  state.  The ERFA version is not subject to this restriction and
-**  therefore can be included in distributions which do not support the
-**  concept of "read only" software.
-**  
-**  Although the intent is to replicate the SOFA API (other than
-**  replacement of prefix names) and results (with the exception of
-**  bugs;  any that are discovered will be fixed), SOFA is not
-**  responsible for any errors found in this version of the library.
-**  
-**  If you wish to acknowledge the SOFA heritage, please acknowledge
